1、首先安装好VS软件和QT库，将其配置好，具体不在此展开说明。
2、文件结构如下图：
3、绘制棋盘代码，如下：
void Qwzq::paintEvent(QPaintEvent* event)
{QPainter painter(this);painter.setRenderHint(QPainter::Antialiasing, true);//防锯齿QBrush brush;brush.setStyle(Qt::SolidPattern);for (int i = 0; i < kGridCount+1; i++){painter.drawLine(kBoardMargin,kBoardMargin+i*kBlockSize,size().width()-kBoardMargin,kBoardMargin+i*kBlockSize);painter.drawLine(kBoardMargin+i*kBlockSize, kBoardMargin,kBoardMargin+i*kBlockSize,size().height()-kBoardMargin);}for (int i = 0; i < kGridCount; i++){for (int j = 0; j < kGridCount; j++){if (game->gameMap[i][j] == 1){brush.setColor(Qt::white);painter.setBrush(brush);painter.drawEllipse(kBoardMargin+kBlockSize*j-kRadius,kBoardMargin+kBlockSize*i-kRadius,kRadius*2,kRadius*2);}else if (game->gameMap[i][j]==-1){brush.setColor(Qt::black);painter.setBrush(brush);painter.drawEllipse(kBoardMargin + kBlockSize * j - kRadius, kBoardMargin + kBlockSize * i - kRadius, kRadius * 2, kRadius * 2);}}}QString str;if (game->isWin(clickPosRow, clickPosCol)){str = "Win!";QMessageBox::StandardButton btnValue = QMessageBox::information(this, tr("result"), str);close();}if (game->isDead()){str = "Over!";QMessageBox::StandardButton btnValue = QMessageBox::information(this, tr("result"), str);close();}
}4、绘制旗子代码，如下：
void Qwzq::mousePressEvent(QMouseEvent* event)
{int x = event->x();int y = event->y();int kr = kBoardMargin + kBlockSize * kGridCount;int kd = kBoardMargin + kBlockSize*kGridCount;if (x>=kBoardMargin&&x<=kr&&y>=kBoardMargin&&y<=kd){int x1 = (x - kBoardMargin) / kBlockSize;int y1 = (y - kBoardMargin) / kBlockSize;x1 = x - (kBoardMargin + kBlockSize * x1);y1 = y - (kBoardMargin + kBlockSize * y1);if (x1 > kBlockSize / 2)x = (x-kBoardMargin) / kBlockSize + 1;elsex = (x - kBoardMargin) / kBlockSize;if (y1 > kBlockSize / 2)y = (y-kBoardMargin) / kBlockSize + 1;elsey = (y - kBoardMargin) / kBlockSize;game->updateMap(y, x);clickPosRow = y;clickPosCol = x;}update();
}5、gameModel.cpp代码如下：
#include"GameModel.h"
#include<utility>
#include<qDebug>void GameModel::startGame()
{gameMap.clear();for (int i = 0; i < kBoardSize; i++){std::vector<int> lineBoard;for (int j = 0; j < kBoardSize; j++){lineBoard.push_back(0);}gameMap.push_back(lineBoard);}playerFlag = true;
}void GameModel::updateMap(int row, int col)
{if (playerFlag)gameMap[row][col] = 1;elsegameMap[row][col] = -1;playerFlag = !playerFlag;
}void GameModel::actionByPerson(int row, int col)
{updateMap(row,col);
}bool GameModel::isWin(int row, int col)
{//水平方向检查for (int i = 0; i <= kBoardSize - 5; i++){if (gameMap[row][i] == 1||gameMap[row][i]==-1){if (gameMap[row][i] == gameMap[row][i + 1]){if (gameMap[row][i + 1] == gameMap[row][i + 2]){if (gameMap[row][i + 2] == gameMap[row][i + 3]){if (gameMap[row][i + 3] == gameMap[row][i + 4]){return true;}}}}}}//竖直方向检查for (int i = 0; i <= kBoardSize - 5; i++){if (gameMap[i][col] == 1 || gameMap[i][col] == -1){if (gameMap[i][col] == gameMap[i+1][col]){if (gameMap[i+1][col] == gameMap[i+2][col]){if (gameMap[i+2][col] == gameMap[i+3][col]){if (gameMap[i+3][col] == gameMap[i+4][col]){return true;}}}}}}//135度方向检查int krow = kBoardSize -1- row;if (krow <= col){int i_135 = row + krow;int j_135 = col - krow;for (j_135; j_135 <= kBoardSize - 5; j_135++){if (gameMap[i_135][j_135] == 1){if (gameMap[i_135][j_135] == gameMap[i_135 - 1][j_135 + 1]){if (gameMap[i_135 - 1][j_135 + 1] == gameMap[i_135 - 2][j_135 + 2]){if (gameMap[i_135 - 2][j_135 + 2] == gameMap[i_135 - 3][j_135 + 3]){if (gameMap[i_135 - 3][j_135 + 3] == gameMap[i_135 - 4][j_135 + 4]){return true;}}}}}i_135--;}}if (krow > col){int i_135 = row + col;int j_135 = col - col;for (i_135; i_135 >= 4; i_135--){if (gameMap[i_135][j_135] == 1){if (gameMap[i_135][j_135] == gameMap[i_135 - 1][j_135 + 1]){if (gameMap[i_135 - 1][j_135 + 1] == gameMap[i_135 - 2][j_135 + 2]){if (gameMap[i_135 - 2][j_135 + 2] == gameMap[i_135 - 3][j_135 + 3]){if (gameMap[i_135 - 3][j_135 + 3] == gameMap[i_135 - 4][j_135 + 4]){return true;}}}}}j_135++;}}//45度方向检查if (row >= col){int i_45 = row - col;int j_45 = col - col;for (i_45; i_45 < kBoardSize; i_45++){if (gameMap[i_45][j_45] == 1){if (gameMap[i_45][j_45] == gameMap[i_45 + 1][j_45 + 1]){if (gameMap[i_45 + 1][j_45 + 1] == gameMap[i_45 + 2][j_45 + 2]){if (gameMap[i_45 + 2][j_45 + 2] == gameMap[i_45 + 3][j_45 + 3]){if (gameMap[i_45 + 3][j_45 + 3] == gameMap[i_45 + 4][j_45 + 4]){return true;}}}}}j_45++;}}if (row < col){int i_45 = col - row;int j_45 = col - row;for (j_45; j_45 < kBoardSize; j_45++){if (gameMap[i_45][j_45] == 1){if (gameMap[i_45][j_45] == gameMap[i_45 + 1][j_45 + 1]){if (gameMap[i_45 + 1][j_45 + 1] == gameMap[i_45 + 2][j_45 + 2]){if (gameMap[i_45 + 2][j_45 + 2] == gameMap[i_45 + 3][j_45 + 3]){if (gameMap[i_45 + 3][j_45 + 3] == gameMap[i_45 + 4][j_45 + 4]){return true;}}}}}i_45++;}}return false;
}bool GameModel::isDead()//死局，即棋盘被下满了
{for(int i=0;i<kBoardSize;i++)for (int j = 0; j < kBoardSize; j++){if (gameMap[i][j] == 0)return false;}return true;
}
6、gameModel.h代码如下：
#ifndef GAMEMODEL_H
#define GAMEMODEL_H#include<QObject>
#include<vector>enum GameStatus
{playing,win,dead
};const int kBoardSize = 15;class GameModel
{
public:public:std::vector<std::vector<int>>gameMap;bool playerFlag;GameStatus gameStatus;void startGame();void actionByPerson(int row, int col);void updateMap(int row, int col);bool isWin(int row, int col);bool isDead();};
#endif // !GAMEMODEL_H
7、Qwzq.cpp代码如下：
#include "Qwzq.h"
#include <QMouseEvent>
#include <QMenuBar>
#include <QPainter>
#include <QDebug>
#include<QMessageBox>const int kBoardMargin = 30;
const int kRadius = 15;
const int kBlockSize = 40;
const int kGridCount = 15;Qwzq::Qwzq(QWidget *parent): QMainWindow(parent)
{//ui.setupUi(this);setFixedSize(kBoardMargin * 2 + kGridCount * kBlockSize, kBoardMargin * 2 + kGridCount * kBlockSize);setMouseTracking(true);QMenu* gameMenu = menuBar()->addMenu(tr("Game Model:"));QAction* actionPVP = new QAction("PVP", this);menuBar()->addAction(actionPVP);connect(actionPVP, SIGNAL(triggered()), this, SLOT(initPVPGame()));initGame();
}void Qwzq::initGame()
{game = new GameModel;initPVPGame();clickPosRow = clickPosCol = 0;
}void Qwzq::initPVPGame()
{game->gameStatus = playing;game->startGame();
}Qwzq::~Qwzq()
{if (game){delete game;game = nullptr;}}void Qwzq::paintEvent(QPaintEvent* event)
{QPainter painter(this);painter.setRenderHint(QPainter::Antialiasing, true);//防锯齿QBrush brush;brush.setStyle(Qt::SolidPattern);for (int i = 0; i < kGridCount+1; i++){painter.drawLine(kBoardMargin,kBoardMargin+i*kBlockSize,size().width()-kBoardMargin,kBoardMargin+i*kBlockSize);painter.drawLine(kBoardMargin+i*kBlockSize, kBoardMargin,kBoardMargin+i*kBlockSize,size().height()-kBoardMargin);}for (int i = 0; i < kGridCount; i++){for (int j = 0; j < kGridCount; j++){if (game->gameMap[i][j] == 1){brush.setColor(Qt::white);painter.setBrush(brush);painter.drawEllipse(kBoardMargin+kBlockSize*j-kRadius,kBoardMargin+kBlockSize*i-kRadius,kRadius*2,kRadius*2);}else if (game->gameMap[i][j]==-1){brush.setColor(Qt::black);painter.setBrush(brush);painter.drawEllipse(kBoardMargin + kBlockSize * j - kRadius, kBoardMargin + kBlockSize * i - kRadius, kRadius * 2, kRadius * 2);}}}QString str;if (game->isWin(clickPosRow, clickPosCol)){str = "Win!";QMessageBox::StandardButton btnValue = QMessageBox::information(this, tr("result"), str);close();}if (game->isDead()){str = "Over!";QMessageBox::StandardButton btnValue = QMessageBox::information(this, tr("result"), str);close();}
}void Qwzq::mousePressEvent(QMouseEvent* event)
{int x = event->x();int y = event->y();int kr = kBoardMargin + kBlockSize * kGridCount;int kd = kBoardMargin + kBlockSize*kGridCount;if (x>=kBoardMargin&&x<=kr&&y>=kBoardMargin&&y<=kd){int x1 = (x - kBoardMargin) / kBlockSize;int y1 = (y - kBoardMargin) / kBlockSize;x1 = x - (kBoardMargin + kBlockSize * x1);y1 = y - (kBoardMargin + kBlockSize * y1);if (x1 > kBlockSize / 2)x = (x-kBoardMargin) / kBlockSize + 1;elsex = (x - kBoardMargin) / kBlockSize;if (y1 > kBlockSize / 2)y = (y-kBoardMargin) / kBlockSize + 1;elsey = (y - kBoardMargin) / kBlockSize;game->updateMap(y, x);clickPosRow = y;clickPosCol = x;}update();
}
8、Qwzq.h代码如下：
#pragma once#include <QtWidgets/QMainWindow>
#include "ui_Qwzq.h"
#include <GameModel.h>class Qwzq : public QMainWindow
{Q_OBJECTpublic:Qwzq(QWidget *parent = nullptr);~Qwzq();GameModel* game;int clickPosRow, clickPosCol;void initGame();private slots:void initPVPGame();private:private:Ui::QwzqClass ui;void paintEvent(QPaintEvent* event);void mousePressEvent(QMouseEvent* event);
};
9、main.cpp代码如下：
#include "Qwzq.h"
#include <QtWidgets/QApplication>int main(int argc, char *argv[])
{QApplication a(argc, argv);Qwzq w;w.show();return a.exec();
}
10、运行界面如下：
